Well, this varies from day to day, but is mostly the same.
After work, I get home and usually log onto WoW.
I repost any expired auctions as well as cancelling and reposting my gems.
Then I decided what I want to do from there. If all of my friends are online, we will run something together. Often times it is an instance, but last night we went into Uldum.
Lately, I have also been playing a decent amount of Diablo 3. While I am doing that, my wife will usually be playing on one of her varios WoW characters.
Sometimes I get the first shooter bug and play some MW3.
It really depends on my mood, but I think around 80 percent of my gaming time is spent in WoW.
